Gowanda’s 121KM5002H is a horizontally open construction toroidal inductor designed for high reliability and performance. It features a weight of 11 grams and dimensions of 20.83 × 20.83 × 10.16 mm, making it suitable for various applications. Part of the KM series, this inductor is mounted using through-hole technology (THT) and is classified under the COTS+ application grade, ensuring it meets commercial off-the-shelf standards with enhanced reliability. It offers an inductance of 50 µH, a direct current resistance (DCR) of 0.03 Ω, and a self-resonant frequency (SRF) of 4 MHz. The current rating is 4.77 A DC, with incremental current limits of 2300 mA DC for a 10% inductance change and 4000 mA DC for a 20% change. The inductor has a tolerance of ±10% and features leaded terminations with a Sn63Pb37 finish. It operates within a temperature range of -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in bulk packaging.
